Description
Technical field
The present invention relates to for piston, be positioned at the lubrication system of the device of cylinder body according to the preamble of claim 1.The invention still further relates to explosive motor, relate to particularly and there is the big-block engine that is positioned at the device of cylinder body with the piston of lubrication system.
Background technique
Big-block engine, be specifically the big-block engine of large-sized diesel motor form usually as driver element peculiar to vessel or for Fixed Point Operation, for example drive big-block engine to produce electric energy, described big-block engine can be designed to two-stroke internal combustion engine or four-stroke ic engine.In this, big-block engine conventionally within the quite long cycle with the operation of working muchly, this has high request to job security and validity.Therefore particularly, long maintenance intervals, low wearing and tearing and economic treatment fuel is central standard for operator.
In working order, piston is along the wall slip that is used as running surface and conventionally makes cylinder sleeve form of cylinder body.In this, provide lubricating cylinders or piston lubrication.On the one hand, piston must as far as possible easily slide in cylinder body, that is to say not hinder to slide; On the other hand, piston as far as possible closely converts mechanical work to the energy efficient of guaranteeing to discharge in combustion process in the combustion space in sealed cylinder block.
For this reason, the oiling agent of form that is conventionally lubricant oil in the duration of work of large-sized diesel motor is introduced into cylinder body to obtain the good roadability of piston and to keep the wearing and tearing of running surface of piston and piston ring low as far as possible.In addition, lubricant oil is used for erodibility products of combustion and for avoiding corrosion.Due to these numerous requirements, very senior and expensive material is usually as oiling agent.
Therefore, the work for the special efficient and cost-effective of motor, need to carry out work with as far as possible little oiling agent consumption.Oiling agent consumption is understood to the amount of the oiling agent that lubricated work is die on for reality, that is to say by greasing and is consumed, the amount of being lost.Because oiling agent is absorbed as drop or distributes along inboard wall of cylinder block as lubricant film in combustion gas, also can cause this loss.Therefore this oiling agent can enter in combustion space with gas form or liquid form, can in combustion space, light and can be burned, and this effect itself is undesirable, and this is because it can cause the sediments in back-fire or cylinder interior space.
Verified greasing is so-called internal lubrication, and wherein the inside of oiling agent by piston is transferred and is then applied on piston or by one or more the surperficial lubricant housings that is arranged on piston and is applied on cylinder body running surface.Such process is for example disclosed in EP A0903473.
Known have multiple possibility in order to oiling agent is fed to the inboard wall of cylinder block of reciprocating piston type internal combustion motor.For example document EP2133520A1 and EP2253810A1 show and have the lubricating fitting that is arranged in the lubricant reservoir in piston itself.Therefore these schemes relate to by piston oiling agent are fed to lubricant housings.
Taked different settling modes to reduce oiling agent demand.On the one hand, oil collecting ring is set, such as from for example EP2133520A1 or known from EP1936245A1.This means by means of oil collecting ring to avoid oiling agent to enter in combustion space.
Alternatively or in addition, oiling agent also can be supplied to the slip surface of the piston in cylinder interior space and also can be received in the notch in cylinder sleeve itself, such as disclosed in EP2050946A1 by cylinder sleeve itself.
The metering of the lubricating cylinders of two-stroke marine diesel engine by oiling agent injected and carried out, and wherein current conventional lubrication system is due to the pump of delivered constant capacity distribute lubricant ideally, and only approximately every 10 revolutions are injected.Relatively long pipeline between pump and nozzle has also reduced the dynamics of system, that is to say, oversize for covering the time that the metrical pulse of the path distance from pump to oiling agent injection element needs, so that can not be by pump fine adjustment injection length.In addition, length increase along with connecting line, the loss causing due to pipe friction increases, and makes to be no longer detected due to the elasticity of oiling agent in the pulse of the ingress of lubricant injection valve, and the elasticity of this oiling agent is that the compressibility in connecting line causes by it.
WO0235068A1 shows the oiling agent injection element of fluid-actuated.In this case, must there is sufficiently high hydrodynamic pressure for regulating oiling agent to inject.In addition must take measures to make pressure fluid and oiling agent to flow in passage separated from one another.This hydrodynamic pressure utilizes pump to produce according to this mode of execution, and this pump is attached to oiling agent injection element and is driven by its motor.According to this scheme, therefore for each oiling agent injection element, need pump and motor.If a plurality of oiling agent injection elements are set, therefore this scheme causes the maintenance man-hours of increase and the investment cost of increase so.Therefore this scheme may not be suitable for multicylinder engine, especially for boats and ships big-block engine.On the one hand, maintenance man-hours must be the least possible, and this is because motor must be in the whole travel time of ship moved working for a long time.This means, for standby, a plurality of such fluid-actuated oiling agent configuration elements must maintain stock redundantly.On the other hand, investment cost should keep low as far as possible.
The possibility that a plurality of pumps and motor are distributed by by so-called common rail system for providing to oiling agent injection element supply oiling agent.WO2011116768A1 shows such for oiling agent being injected into the common rail system of a plurality of cylinder bodies of explosive motor.In this system, the foregoing problems of connecting line is solved, and the metering of oiling agent is directly carried out in lubricating element by magnet-controlled valve.Utilize these magnet-controlled valves can accurately regulate the supply of oiling agent, and the endurance that in fact subtend cylinder body is supplied the time of oiling agent and supplied oiling agent, the two regulated, that is to say, the amount that should be supplied to the oiling agent of lubricant housings can accurately be regulated.Yet, by the magnet-controlled valve for this object, must guarantee that oiling agent supply can the connection of oiling agent nozzle starts and oiling agent supplies again to interrupt by opening to.According to lubricant pressure, the interruption of oiling agent supply can be different length, until reach closing pressure, that is to say, by regulating, makes the oiling agent volume that arrives oiling agent position that the volume that will provide is provided.Naturally, can set the pressure-dependent switching action of magnet-controlled valve, yet this means the adjusting man-hour (regulation effort) of increase.
